SECTION 3: SETUP CONFIGURATION

Border In-ll

When the camera moves, the output frames are shifted to keep the image features aligned to previous frames. This results in areas

for which there is no image data available. The Border In-ll combo box lets you select what happens to those areas of the image.

There are 5 options available:

• Fast Fade: [Default] Newer frames are composited on top of older frames. The old frames are quickly faded to black. This

mode is most suited to PTZ and xed cameras.

• Slow Fade: Newer frames are composited on top of older frames. The old frames are slowly faded to black.

• No Fade: Newer frames are composited on top of older frames. The old frames are not changed. This option is suitable for

xed cameras where there exists minimal movement by people and cars around the edge of the scene.

• Fixed: A xed size black border is present on all sides which blanks out the moving edges of the image. The size of the borders

is equal to the maximum frame shift (see below).

• None: Old frames are not displayed. Regions of the output image for which there is no available data are lled with black.

Camera Installation Mode

The camera installation mode has 3 options:

• Fixed/PTZ: [Default] The stabilization algorithm parameters are optimized to give the best stabilization results for xed/PTZ

cameras.

• In vehicle/Hand held: The stabilization algorithm parameters are optimized for best stabilization performance for cameras

where the camera xture experiences continued, large displacements or scene changes. E.g. when used in a moving vehicle.

• Low Frequency Stabilization: The Fixed/PTZ and In vehicle/hand held stabilization modes are designed to allow tracking

of intentional camera panning by not stabilizing low frequency movements (< 1Hz). The Low Frequency mode has a lower

cut-o frequency to allow better low frequency stabilization at the expense of worse tracking of intentional movement.

This mode will automatically switch to the higher frequency mode when excessive movement in one direction is detected

to produce better tracking of intentional movement. When the movement stops, the mode reverts to Low Frequency

Stabilization.

Auto Disable

Auto disable provides 2 options:

• Pan/Tilt: This option disables stabilization when excessive pan or tilt motion is detected. Stabilization is reactivated 3 seconds

after panning stops.

• Low Detail: When this option is enabled, the algorithm is disabled when a scene with insucient detail for reliable

stabilization is detected. This prevents the image position ‘hunting’ when there is very little scene detail. For example, when

the camera is pointed at a completely blank wall the stabilized image will jump around slightly because it is locking on to the

random video noise. Similar hunting problems can occur in other situations where a large part of the scene lacks suitable detail

for Stabilizer lock.
